I couple of days ago I've upgraded from 8 (jessie) to 9 (stretch) taking care of removing third-party repositories before upgrading, in my /etc/apt/sources.list file, which is now as follows:
deb http://deb.debian.org/debian/ stretch main contrib non-free deb http://security.debian.org/ stretch/updates main contrib non-free deb http://deb.debian.org/debian/ stretch-updates main contrib non-free deb http://ftp.debian.org/debian stretch-backports main contrib deb https://dl.winehq.org/wine-builds/debian/ stretch main The upgrade went decently well (system is booting) but I've noticed some incongruences with apt and aptitute while installing winehq-staging which led me thinking some old packages were still in the system. So I performed (I think) a cleanup of the packages which are not included in the current repositories, with the command: aptitude search ?obsolete > mylist and then removing the resulting packages. My system now 'looks' clean, but for example mpv (media player) is not working: user@linux:~$ ldd /usr/bin/mpv|grep -i "not found" libwebp.so.5 => not found libx265.so.102 => not found libopenjpeg.so.5 => not found libgnutls-deb0.so.28 => not found libcrypto.so.1.0.0 => not found libvidstab.so.1.0 => not found libnppi.so.7.5 => not found and I have no idea why /usr/local/lib/libavcodec.so.57 is liked with libwebp.so.5: root@linux:~# ldd /usr/local/lib/libavcodec.so.57|grep -i found libwebp.so.5 => not found libx265.so.102 => not found libopenjpeg.so.5 => not found as it looks like it's the current version as the upstream: root@linux:~# dpkg -l|grep avco ii libavcodec57:amd64 7:3.2.12-1~deb9u1 amd64 FFmpeg library with de/encoders for audio/video codecs - runtime files ii libavcodec57:i386 7:3.2.12-1~deb9u1 i386 FFmpeg library with de/encoders for audio/video codecs - runtime files please help ? Thank you, Mike
